Studies of Richard Réti

hi everybody. I come from the town where Richard Réti was born. I own one of books about him (Jan Kalendovský - Richard Réti, the chess thinker) and there are 55 of hist best studies.

I'll start with the well-known and easy ones, later I can share them all if there is a good response.

Have fun!!

#1 White to move and draw (the most famous study of all time)

#2 Black to move, White to draw.

#3 White to move and draw in an unbelievable position.

#4 White to move and draw.

Post your solution, when all 4 will be solved, I'll post the next 4 with knights also involved.

Thanks!  I love endgame compositions, and am studying the late-great Mario Matous.

#1 is of course a classic. One of my favorites.

puzzle number 3

hi man. for example:

it is absolutely amazing at the first glance, even if you know study #1. Are you interested in the other studies? There are some pretty amazing ones..
