Subject: A tough one?

Author: Jim Monaghan

Hi,

This one is pretty difficult. The idea is to avoid the tempting 1.Rxe5 which
seemingly wins a pawn, but in reality drops the exchange for a pawn. The main
line of the combo runs 20 ply. One of the rare occasions where Lasker stumbled.
Any engines "smart enough" to avoid the trap and understand why in reasonable
time?

[Event "Moscow"]
[Site "USSR"]
[Date "1936"]
[Round "?"]
[White "Lasker"]
[Black "Ragozin"]
[Result "0-1"]
[SetUp "1"]
[FEN "2r3k1/1q1r1pbp/p4np1/Bp1bp3/8/P1N2P1P/1PP2QP1/3RRBK1 w - -"]
