Junior5 needs 8 minutes and 33 seconds to find Re2 at iteration 16 after searching 66123 Knodes Junior5.3 needs 9 minutes and 9 seconds to find Re2 at iteration 16 after 73089 Knodes. on the other hand Junior5.3 can finish iteration 15 after 3 minutes and 16 seconds when Junior5 needs 3 minutes and 24 seconds to finish iteration 15. This is probably the reson that Junior5.3 can find the move if I give it time control of 1 hour per 10 move+2 hours per 20 moves when Junior5 cannot find Re2 with the same time control. Junior5 and Junior5.3 do not see that Rxe8 is losing and reject it for positional reasons. Junior5's evaluation is 0.05 advantage for white at depth 16 and reject it because Re2 gives white 0.19 pawn advantage and Junior5.3 has better positional understanding and evaluates Re2 as 0.13 advantage for black at iteration 16 Uri
