Hehe. Nice

Oh, really nice!

Ha nice.  Yeah, f3 was pretty bad in general...

Nice one erik, I love the the tactics trainer too.

slick

Nice. I know you as the owner of this site won't appreciate this, but I would never recommend to a student any online tactics trainer that generates positions mostly randomly (from what I've heard) and doesn't give one a chance to try the same positions again and again. Of course doing any kind of tactical training will improve one's game anyway, but to really drill the patterns into the mind I believe puzzle books are best. The positions are less randomly generated, one's not tempted to rush without understanding the position just to get a better score and I think most importantly one can work on specific chapters again and again until they've got all of the positions memorised. Also, for me staring at a screen for half an hour or more just isn't very pleasant..

Just my opinion.

Nice use of the 2 Bishops and attacking an undefended King

Nice

You are certainly not a modest winner Erik!  If we ever play, please x out my game unless its a win!  lol

I love the tactics trainer, but I have trouble moving fast enough.

Nice One

sorry to toot my own horn, but i had another tactics trainer moment just now. i saw this when i played Qh5. i knew he wouldn't be able to resist the thought of "winning a piece" (forking bishop on c4 and rook on h1).

fun!

(FYI - i've already set the conditional moves to win in either case)

Nice job erik!

Here's a suggestion though, and one that picks up from atomichicken's: Add to the tactics trainer so that users are able to choose problem sets that they can practice over and over again, so that they get the patterns more easily. Maybe this would need tactics categorization so that, say, I would choose 20% of the problems in my problems set to be forks, 20% skewers, 20% decoys, etc.

This might obviously go into the premium features but it's definitely worth it if it's there.

I second that. I think it would set your tactics trainer apart from the other free ones out there.

That's not to say that the feature I mentioned should go into premium at its current price -- I understand that at present the premium membership already gives a whole darn load of value already. Maybe another membership level?
