4 player tactics

First position I think the 20 points + eliminating side player is definitely worth the Queen for red, and I agree that between good players this will be considered standard and so (if not for what I'll say next) as yellow in a high level game I'd take blue's queen if he doesn't prevent it next move.

The problem in this position is that after red mates blue on b7, when yellow takes red's queen it's check and it can end up in a lot of damage for red depending on green's third move, so I wouldn't risk it as yellow.

Nc6 might also be an easy move for blue in the first position. A move I missed at first.

Shit, in the second position I think green is completely lost.

Ql8 only move? And still in big trouble

He can hope blue would help him by sacrificing a bishop to deny yellow the mate, but yes. Looks quite hard for green.

I will remember that second position as scholars mate for teams. It's that good!

2. ... ... ... Nl8

3.Nxm5+ Bxh13+ Bxh13 Bxm8 might be a possible line

i think so too! i think he's forced to defend on move 1 (before red has even launched his pony!)

i missed QI8!

in teams, blue can still check yellow

i keep the play teams version in mind of course, but i suspect lots of it translates to our current game. it also seems not easy for green/yellow to help defend eachother.

as blue, would you check yellow (costs a bishop) to avoid green getting mated? to avoid being in the sandwich?

After Nc6 blue can be matted immediately by the yellow queen and the red bishop. +20 for red, at the cost of the bishop. +5 for yellow.
The mate was available one move earlier though, so blue could hope that it will remain unnoticed?

Nc6, Qc9 and green can't even prevent Bb9#. he can only up the price for red to mate blue.

@Skeftomilos, very true

@_-__-__-___-, not sure if I would sac the bishop. I think I would, but I'd be very hesitant and not sure if it is correct. If it was 2 vs 2 I would not hesitate though

btw thread that got me started https://www.chess.com/clubs/forum/view/question-6

we could also remove that option by having blue not have opened that diagonal. for the puzzles sake.

made some adjustments

#1 blue

#2 green

hmm have we missed k9 for green in #2?

I watched a game in which this postition was developed and red had the next move:

(A few steps later red was been checkmated.)

But at this point, I think, red had a nice move: Qxc11! It hits a pawn, give double check and blue king can't capture red queen, bacause it is protected and after blue Ka10 (there is nothing else) gold can't capture also, because blue rook protects the queen. So after gold Kd13 red queen can escape.

I like these moments in four player chess.

That does look like a nice move. However I think it is only worth 6 points and does not solve any of reds problems like how to deal with blue advancing the pawn on the 2nd rank. Might still be a good move though.

If you want to be really fancy you could  go for:

1.Qxc11+ Ka10 Kd13 ...

2.Qe13+ Qh13# ... ...

3.Qxh13

Of course that plan would really backfire if blue does not play the checkmate and I guess he should not. He might just play 2...Qe4 for example when he will win yellows queen and red lose his queen.

Very nice, venbagoly!
(But Ka10, not Kb10. Then yellow Kd13.)

Martin0, Kd10? Perhaps Kd13.

coordinates are hard  I still sometimes mess up in classical chess and with this big board things are not easier. I edited my post.
