Makruk and Seirawan are "extremely" simple. But an 1800 elo player has no chance of playing perfectly.
Seirawan chess is not simpler than FIDE chess. The rules are a superset of FIDE rules and the game tree is bigger too. I don't know about Makruk but it looks about the same as FIDE chess.
In this thread, I'm looking for chess-like games with difficulty near to that of checkers. Consider the following table
Tree size isn't a perfect figure of merit for game difficulty, but it's a decent one. And you can argue over the precise values for game size etc. here. But this gives some basis for comparison.
FIDE chess is actually the simplest chess-like game listed. By chess-like, I mean a game having two symmetrical armies of picees that move and capture, each with a King piece whose capture decides the game.

I got confused and said Seirawan rather than Sittuyin.
So forgot I said Seirawan.
Makruk has different pieces than FIDE chess.
The Queen is a Ferz.
Bishop moves like a silver general in Shogi.
This isn't perfect either but on Variantfishtest Fairy-Stockfish manages a 90% drawrate with Sittuyin and a 85% drawrate with Makruk.
That's with 10s+0.1s at 1 mnps. And those variants aren't quite as optimized as the real SF.
Shatranj is similarly simple (and drawish) because of weak pieces.

Ah, thanks. I'll look closer at Makruk and I had not heard of Sittuyin.
There are chess variants that use a smaller board and fewer pieces, and these no doubt have a much smaller game tree. E.g. Los Alamos Chess (6x6, bo Bishops).
