I will predict Stockfish 180813 will win this tournament, my early testing suggest at faster time controls. Stockfish 180813 has surpassed Houdini 3, and Houdini 3 may no longer be the strongest chess engine. I doubt a longer time control on much faster hardware will change the results, going by past Stockfish testing.

It will be interesting to watch...

At what level "faster time controls" and with how many cores did you test? Have you run a significant number of games? At bullet speeds, the latest SF still lags behind Komodo 5.1r2 by about ten elo based on 2k games, and of course in bullet chess Komodo is no match for Houdini 3. Since both Komodo and SF gain on Houdini with increased depth, this should be a pretty close contest.

Are you sure there's no EGTB ?

I saw Houdini announced a mate in 34 against Komodo in an EG KQPKQP :

Are you sure there's no EGTB ?

I saw Houdini announced a mate in 34 against Komodo in an EG KQPKQP :

86.Kh3 -#34/1 0 Kb6 -8.01/22 11 87.Qb3+ -#33/1 0 Qb5 -#33/1 0 88.Qe3+ -#32/1 0 Kc7 -#32/1 0 89.Qf4+ -#31/1 0 Kb7 -#31/1 0 90.Qf7+ -#30/1 0 Kb6 -#30/0 0 91.Qf6+ -#29/1

looks like it was Komodo 86.Kh3 -#34/1 Kb6 -8.01/22
Houdini sees it next move 87.Qb3+ -#33/1 Qb5 -#33/1

yes, I am sure no EGTB is used at all.
If they would have been used, you will see the usage in the header of the PGN after the kNs.
Only the GUI uses all 3-4-5men and some 6 men (80Gb) in total.
